57 SVALVE:AOPEN:<RI>,<OT>,<FA>,<NL>,<NP>,<DL>
Description:
With this command, both of the parameters “Rising” and “Falling” are
specified in steps of 1/100 ms, in contrast to the other time parameters
(1/10 ms).
Specified values must be integer and positive. To choose the external
mode, enter “EXTERNAL” for “Open Time”, instead of a numerical value.
You have to include all six setup parameters.
Parameters previously entered by “TRIGGER:ASET” are not erased, but the
combination remains in the system only until the end of the cycle. If you do
not wish to reenter the entire command several times, the “TRIGGER:ASET”
command is advantageous. This way the cycle can be reactivated simply by
“SVALVE:AOPEN”.
This command works just like its “VALVE” variant. Only the MDC does not
answer with “OK”, but with the parameters, which were used to trigger.
This way the machine software can check the parameters directly.
Important Note!
In case you trigger a dispensing process in the Infinite Mode with this
command, you cannot stop it via the RS232C interface. You can only stop it
via the PLC interface or by pressing the [esc]-key on the MDC.
Example:
Input:
SVALVE:AOPEN: 30,10,15,80,20,15
Result:
The dispensing cycle contains the following values:
Rising: 30 ≙ 0.3 ms (ms = Millisecond)
Open Time: 10 ≙ 1.0 ms
Falling: 15 ≙ 0.15 ms
Needle Lift: 80 %
Number of Pulses: 20
Delay: 15 ≙ 1.5 ms
Return:
30,10,15,80,20,15
58 SVALVE:AOPENS<setup no.>
Description:
This command initiates a dispensing cycle with the parameter combination
of the setup (or scenario) indicated in the command.
You decide to dispense with the parameters of a specified setup (or
scenario, if SCENARIO is “ON”), by using one of the following command
extensions:
• S0 - uses parameters of setup 0 (or scenario 1 with SCENARIO “ON”)
• S1 - uses parameters of setup 1 (or scenario 2 with SCENARIO “ON”)
• S2 - uses parameters of setup 2 (or scenario 3 with SCENARIO “ON”)
• S3 - uses parameters of setup 3 (or scenario 4 with SCENARIO “ON”)
These parameters are used even with activated select pins. As an example,
to dispense with the parameters of setup 2 you have to enter the following
command:
SVALVE:AOPENS2
For this example, SCENARIO has to be “OFF” in the menu.
This command works just like its “VALVE” variant. Only the MDC does not
answer with “OK”, but with the parameters, which were used to trigger.
This way the machine software can check the parameters directly.
Important Note!
In case you trigger a dispensing process in the Infinite Mode with this
command, you cannot stop it via the RS232C interface. You can only stop it
via the PLC interface or by pressing the [esc]-key on the MDC.
Example:
Input:
SVALVE:AOPENS2

Result:
The system launches a dispensing cycle, using the
parameters given by the selected setup (or scenario; for
further information about scenarios and the select pins, see
paragraph 7.9, page 70).
Return:
50,20,20,80,1,10

59 WRITE:LCD:<text> (LCD = Liquid-crystal display)
Description:
With this command, an ASCII text including up to 32 characters can be writ-
ten on the screen. All the letters appear in form of capital letters.
Example:
Input:
WRITE:LCD:Hello World
Result:
The display shows:
HELLO WORLD
Return:
OK
60 TAPPET:SET:<value>
Description:
This command allows you to decide on the number of cycles until the next
tappet maintenance. If no numerical selection is made, the value will be
“infinite”.
Example:
Input:
TAPPET:SET:500000
Result:
500000 cycles have been selected.
Return:
OK
61 TAPPET:CLEAR
Description:
The counter for tappet maintenance is cleared. This command is usually
entered at the end of the maintenance procedure.
Example:
Input:
TAPPET:CLEAR
Result:
Counter reset to “0”.
Return:
OK
62 NOZZLE:SET:<Value>
Description:
This command determines the number of cycles to be performed until the
next maintenance of the nozzle insert. If you do not enter any number, the
value is set as “infinite”.
Example:
Input:
NOZZLE:SET:500000
Result:
500000 cycles have been selected.
Return:
OK
63 NOZZLE:CLEAR
Description:
The content of the nozzle maintenance counter is erased.
Example:
Input:
NOZZLE:CLEAR
Result:
Counter reset to “0”.
Return:
OK
